Figure 2
Ultrasound examination of the lymph-nodes in regio IIA on both sides (upper panel: the lymph node on the right side; lower panel: the lymph node on the left side): The masses showed a widely defined border, a hypoechoic internal pattern with anechoic areas and a dorsal enhancement. No vessels within the lesions could be detected by Doppler-ultrasound and the regular lymph node anatomy with hilum and cortex was depleted. Therefore, the lesions were suspicious of containing metastastic tumor masses.
